ATTORNEYS United States Patent 3,322,387 SCAFFOLD BRACKET ANCHOR JosephA. Fortin, Sr., Somerset, Mass. (48 Winter St, Fall River, Mass. 02720)Filed June 28, 1965, Ser. No. 467,305 6 Claims. (Cl. 248-235) ABSTRACTOF THE DISCLOSURE A lightweight anchor to bridge spaced studs of abuilding structure which anchor is channel shape and reinforced.

This invention relates to scaffolding such as is used by builders tooperate on the side of a building.

Heretofore the scaffold bracket which engaged the outer siding of thebuilding was anchored in place by a rod extending through the siding andpassing through a wooden 2" x 6" which extended across between studs onthe inner side of the building. Such a 2 x 6 was heavy and cumbersome,wore easily and had to be discarded early in its use because it wouldnot withstand many turnings of the nut which engaged it to hold the rodof the scaffold bracket in place.

This invention comprises an improvement in such anchor which improvementis fabricated of sheet stock in a structurally strong manner from metaland is lighter in weight than the solid wooden 2 x 6s heretofore used.It is further supported in its portion placed in tension and by reasonof its material is of much greater wear resistance than heretofore.

One of the objects of the invention is to provide a lightweight anchorfor a scaifold bracket.

Another object of the invention is to provide an anchor which willafford relatively easy turning of the nut which engages it to hold thebracket in place.

Another object of the invention is to so construct the bracket that itwill be resistant to the forces which are applied on it to hold thebracket in place.

Another object of the invention is to provide a structure which will belong lasting and which will withstand the wear to which it is subjected.

With these and other objects in view, the invention consists of certainnovel features of construction as will be more fully described andparticularly pointed out in the appended claims.

In the accompanying drawings:

FIG. 1 is a side elevation of the scaffold bracket showing the same asengaging the side of a building illustrated fragmentally in section andwith the anchor of this invention in place;

FIG. 2 is a sectional view centrally longitudinally through the anchorshowing a fragmental portion thereof;

FIGS. 3 and 4 are sections on lines 33 and 44 of FIG. 2;

FIG. 5 is a central sectional view showing the tension rod as partlyremoved from the anchor; and

FIG. 6 18 a top plan view through the building struct-ure showing theanchor as engaging the spaced studs thereof.

The fragmental portion of the bui'ding comprises a siding 10 withvertical studs 11 supporting the siding. The scaffold bracket designatedgenerally 12- comprises a horizontal arm 14 of generally L-shape havinga hori zontal portion 15 and a strengthening vertical rib 16. Thehorizontal portion 15 is provided with a plurality of openings throughany one of which the upstanding end 17 of the rod 18 may be positionedand held by means of a cotter pin 19. This rod extends through a faceplate 20 at the end of the arm 14 and thence through a hole in thesiding 10 to engage the anchor 30 which is the subject of thisinvention. This arm 14 is also equipped with a leg 21 pivotally attachedto the vertical portion 16 and comprising two parts pivoted together asat 22 and extending to and pivoted to a diagonal brace 23 as at 24, thisbrace also being pivoted at its other end to the arm 14 as at 25. Thisbrace 23 may be L shaped with portions 26 and 27 for mutually stiffeningeach other.

The anchor 30 comprises spaced side walls 31 with the widest portion atmidway of their length. From this widest portion these arms taper totheir ends at the narrow portion 33 along one edge while the arms areperfectly straight as at 34 along their stud engaging edge. A bridgingwall 35 extends along the tapering portions of the side walls and iswelded thereto as at 36 and is turned downwardly at its ends as at 37and there welded to the ends of the side walls 31 as as 38, thusproviding a generally channel shaped structure of tapering shape withstraight edges 34 along one edge thereof. This structure is furtherreinforced by webs 39 at spaced locations usually disposed about halfwaybetween the mid portion of the length of the side walls and their ends.A block 40 which may be tapered as shown in FIGS. 2 and 5 is located atthe mid portion of this anchor and extends from side wall to side walland there welded. A plate 43 is on the outer surface of the bridgingwall 35 at the location of the block 40. A hole 41 extends through theplate 43, the bridging Wall 35 and through the block centrally widthwisethereof so as to provide an opening through which the rod 18 threaded asat 42 may extend.

This anchor is reinforced further by tension rods 45 which are locatedin grooves 46 in the webs 39 and also located in grooves 47 in the block40. This tension rod is hook shaped as at 48 at its ends through whichhook pins 49 extend into the side walls 31, thus securing the tensionrod 45 from the ends of the side wall across the Webs and block in amanner such that a triangular relationship is provided. Thus, throughthe shape of the edge of the side walls which are tapered and provide atriangulation we also have a second triangulation of the tension rod 45with the side walls. It will thus be apparent that when a nut 50 isscrewed onto the threads 42 of the rod 18 and pressure is brought tobear centrally of the anchor toward the siding which is resisted by thestuds 11 which are engaged by the end portions of the anchor, the partof the anchor adjacent the straight edge 34 is placed in tension asthere is a tendency to stretch the edge 34 of the side wall 31, and thiswould be resisted by the rod 45 which is in tension. In this manner theanchor could not readily bend being well supported. Further the taperingof the anchor permits the handle 51 of the nut 50 to be more easilyrotated on the threaded rod by affording greater clearance as suchaction takes place.
